How do I know if a site provides an API?

Question

API

I do TK for getting a job.
There is a site with vacancies in our city.
In the TK, you need to use their API and do some data manipulation.

Answer 1

Ideally, you don’t need to think about it, just give the sites everything, and let them advise what is possible, what is not, what is legal, what is not, if you need a programmer and not a coder, then this approach is preferable. :)
